Abstract

The invention relates to a software radio data transmission system and transmission method based on an LTE signal. Channels are divided into three different physical channels: the synchronization channel, the control channel and the data channel; the system comprises two parts: a transmitter and a receiver; each of the transmitter and the receiver is composed of three parts: an analog radio frequency circuit, a digital baseband circuit, and a digital control circuit; the transmitter is responsible for the data transmission and the receiver is responsible for the data receiving; the transmitterand the receiver can flexibly configure the encoding/decoding schemes, parameter configuration schemes, the channel estimation and detection algorithm configuration schemes and like. The invention designs a hybrid access protocol HE-TDMA with hybrid pre-distribution and random access features at the same time. Through the method and system provided by the invention, a communication system constructed based on the LTE signal can be flexibly configured and used, and the application scene is enhanced at the same time.

Description

technical field [0001] The invention relates to the communication field, in particular to a software radio data transmission system and transmission method based on LTE signals. Background technique [0002] 1. LTE signal. [0003] LTE (Long Term Evolution, long-term evolution) is the long-term evolution of the UMTS technical standard formulated by 3GPP. Its physical layer includes OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing), MIMO (Multi-Input & Multi-Output, Key technologies such as multiple-input multiple-output) and space-time / space-frequency coding can significantly increase the system transmission rate. LTE and its advanced version LTE-A are the core technical standards of the current 4G mainstream, and its physical layer technology will also be an important support for the future 5G system in the frequency band below 6GHz, so its research and development have very important significance and prospects. [0004] The LTE...
